Description

Black tea production is with device that withers

Technical Field

The utility model relates to the technical field of black tea processing equipment, in particular to a withering device for black tea production.

Background

Withering, also known as withering and carving, is a tea making process. The core of the method is that the picked fresh leaves are spread according to a certain thickness and dried in the sun to make the fresh leaves show wilting state. During the withering process, a series of changes occur to the fresh leaves. The moisture of the tea is reduced, and the leaves are changed from crisp and hard to soft, so that the tea is convenient to knead into strips; the activity of enzyme substances contained in the leaves is enhanced, fresh leaf components such as starch, protein, insoluble protopectin, etc. are promoted to be decomposed and converted, effective substances such as glucose, amino acid, soluble pectin, etc. beneficial to the quality of finished tea are generated, and polyphenols are also oxidized to different degrees. The normal and effective withering can eliminate the grass smell of the fresh leaves to generate faint scent, and the fresh leaves have fruit or flower fragrance, so that the finished tea has mellow taste but is not bitter and astringent, and is an important process for preparing the tea. Proper conditions of temperature, humidity and air circulation are required for withering. The first process in the production of tea such as white tea, black tea, oolong tea, etc. is withering, but the degree is different. The white tea has the heaviest withering degree, the water content of fresh leaves is required to be reduced to be below 40%, the black tea has the heaviest withering degree, the water content is reduced to be about 60%, and the green tea has the lightest withering degree, and the water content is required to be between 68 and 70%.

The prior withering method comprises the steps of withering in sunlight, namely uniformly spreading fresh leaves under the sunlight for withering; naturally withering indoors, namely uniformly spreading the fresh leaves on a bamboo curtain or a bamboo sieve, placing the bamboo curtain or the bamboo sieve in a cool and dry place for ventilation; and withering in a withering trough, namely uniformly spreading the fresh leaves on the withering trough for withering.
